Rumor has it that there are seven monsters in Zhang'an: Yishan, Erhai, Sanhe, Sihai, Wuhu, Liuhua, and Qishu.
Yishan lives by collecting firewood. He is a tall, honest man with a kind heart. In his early years, he picked up his second sister Erhai who was frail and sick, took him home and raised her carefully. The second sister's health actually improved day by day.
Erhai has a gentle personality, and she takes care of everyone on weekdays. Unfortunately, her health is not good, so she always spends ten and a half days lying down every time the season changes. One day when Erhai went to the fish market to buy fish, he bumped into Sanhe at Wanjia Ferry who was so hungry that he risked stealing fishermen's things. He stopped the fisherman who was dragging Sanhe to report to the police, paid for her and took her home.
Sanhe has a surly personality and acts deviantly. He often does things to make money, but he has a deep hatred for human traffickers who abduct and sell children. This starts with Sanhe's origin! Sanhe was originally a young lady from a wealthy family. When she was a child, she was playful and sneaked out to go shopping for lanterns during the Lantern Festival. Unexpectedly, she was abducted by a trafficker. Fortunately, Xiao Sanhe was clever. One day when he saw the trafficker drinking too much, he tried his best to escape. After many twists and turns, he finally reached Zhang'an County, and he endured many hardships along the way...
Will their ten-year agreement finally come true?
